Scabies is a common parasitic infection caused by the mite Sarcoptes Scabiei. About 300 million cases of scabies are reported annually. Scabies usually presents clinically with an erythematous excoriated papulovesicular rash, burrows, nodules and hyperkeratotic lesions in specific body areas. A rare presentation of scabies is the bullous pemphigoid-like bullous scabies. So far, to the best of our knowledge, only 32 cases of bullous scabies have been reported in medical literature, of which only 11 were under 60 years of age at the time of initial presentation. This is the first case of bullous scabies being reported from Pakistan. Herein we discuss, with reference to the existing literature, the case of a 23-year-old Punjabi male who presented with a 3 day history of a tense, non-erythematous, non-tender bulla measuring approximately 0.5 cm x 0.8 cm on the right foot near the interdigital cleft. He was diagnosed to have bullous scabies. The diagnosis of scabies should be considered in all patients who present with tense bullous lesions accompanied by pruritus and a maculopapular rash. This is particularly relevant if these lesions do not resolve with steroid treatment. In such patients, in order to prevent a misdiagnosis of bullous pemphigoid, scrapings for Sarcoptes Scabiei mites and eggs should be taken.
Aortic valve stenosis is a disease characterized by thickening and narrowing of the aortic valve (AV), most commonly due to calcification, which leads to left ventricular outflow obstruction called calcific aortic valve disease (CAVD). CAVD presents as a progressive clinical syndrome with cardiorespiratory symptoms, often with rapid deterioration. The modern-day pathophysiology of CAVD involves a complex interplay of genetic factors, chronic inflammation, lipid deposition, and valve calcification, with early CAVD stages resembling atherosclerosis. Various imaging modalities have been used to evaluate CAVD, with a recent trend of using advanced imaging to measure numerous AV parameters, such as peak jet velocity. Significant improvements in mortality have been achieved with transcatheter AV repair, but numerous therapeutics and modalities are being researched to delay the progression of CAVD. This article aims to provide a comprehensive review of CAVD, explore recent developments, and provide insights into future treatments with various novel modalities.
Background: Cardiogenic shock (CS) is a severe complication of acute myocardial infarction (AMI) with high mortality rates. While mechanical circulatory support devices like intra-aortic balloon pump (IABP) and Impella are used to manage CS, their comparative effectiveness remains unclear. This meta-analysis aims to evaluate the safety and efficacy of Impella in the treatment of AMI-associated CS. Methods: A comprehensive literature search was performed across PubMed, EMBASE, Google Scholar, SCOPUS, and Web of Science. The primary efficacy endpoint was 6-month all-cause mortality. Secondary efficacy endpoints included 30-day mortality, major bleeding, limb ischemia, sepsis, and left ventricular ejection fraction. Pooled odds ratios (OR) and standardized mean difference (SMD) with 95% confidence intervals (CIs) were calculated using the random-effects model via Revman version 5.4. Statistical significance was determined at P < .05. Results: Four RCTs with a total of 442 patients were included in this meta-analysis. The pooled analysis showed that the odds of 6-month all-cause mortality were significantly lower with Impella compared to standard of care (OR: 0.64, 95% CI: 0.43–0.95; P value: .03). However, 30-day mortality reported no statistically significant difference between the 2 groups (OR: 1.03; 95% CI: 0.43–2.48; P = .95). Our analysis found that the use of impella is associated with a statistically significant increase in the odds of major bleeding (OR: 3.61; 95% CI: 1.14–11.40; P = .03), limb ischemia (OR: 4.91; 95% CI: 1.37–17.59; P = .01), and sepsis (OR: 2.75; 95% CI: 1.25–6.08; P = .01). No statistical significance was found in left ventricular ejection fraction at follow-up between the 2 groups (SMD: −0.35; 95% CI: −0.78 to 0.07; P = .11). Conclusion: Impella significantly reduces 6-month all-cause mortality in patients with CS following AMI compared to standard of care. However, this survival benefit is offset by a substantial increase in major bleeding, limb ischemia, and sepsis risks associated with Impella. Future large scale trials are needed to validate these findings and refine clinical guidelines for the optimal use of Impella in treating CS.
